The woman, who later turned out to be a schizophrenic without access to her medications, was, by some force, wrestled out and escorted away, then put in a hospital for observation, in a step that was actually safer for everyone than any one of us pressing charges.
pressing charges是后置定语还是动名词复合结构,in a step是修饰谁?之间是什么逻辑关系?
